1. General Physics Lecture 1 1 Welcome to Phys 130! http://www.sos.siena.edu/physics/Current_Courses/PHYS130/ Blackboard blackboard.siena.edu

2. General Physics Lecture 1 2 Physics Physics strives to describe the physical world in terms of the natural laws that govern motion, forces, electricity, etc. The laws are derived from observations and experiment. Once you understand the underlying laws, you can apply them to new situations focus on understanding rather than memorization The laws themselves are often very simple. Applying them can be tricky...

3. General Physics Lecture 1 3 Scientific Method Observations & Experiments Model Theory must make predictions must be testable Testing, testing, testing Simple is better (Occam’s razor)

4. General Physics Lecture 1 4 The Scientific Method It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong. - Richard Feynman

5. General Physics Lecture 1 5 Physics Education Research Physics educators have been working for a decade to improve student learning. They have identified concepts that students find most difficult. allows us to focus our time on what is most challenging for you They have identified active learning strategies that improve student understanding.

8. General Physics Lecture 1 8 About the textbook Your textbook is your #1 resource!!! You are expected to come to class having read the assigned chapter(s). Daily and weekly homework problems will be assigned.

9. General Physics Lecture 1 9 Attendance Policy Students are expected to attend all classes and are responsible for all material covered in class, even when absent. Students should understand that some material discussed in class is not covered in the textbook. In-class quizzes, problems, and activities can not be made up.

10. General Physics Lecture 1 10 Daily Homework Problems Covers new material Daily homework is listed on the schedule Homework is due at the beginning of class No late homework will be accepted Homework grading is effort based Do homework in pencil Returned to you by the next class

11. General Physics Lecture 1 11 Grading Homework Daily homework will be graded on a 5-point scale using the following general guidelines: 5: good effort with correct results and reasoning 4: a good effort with minor errors or a fair effort with no conceptual or math errors 3: a good effort with modest conceptual errors and/or math errors or a fair effort with minor errors 2: a fair effort involving modest conceptual errors or a good effort involving serious conceptual errors 1: a very poor effort 0: no initial effort

12. General Physics Lecture 1 12 Homework Corrections Correct mistakes to homework based on posted solutions Correct mistakes in a different color (blue, green, etc. NOT RED) on previously turned in homework DO NOT rewrite solutions – they will not be accepted Due one week from original due date Maximum correction points you will receive is 2

13. General Physics Lecture 1 13 Weekly Homework Problems Reviews material covered the previous week Due at the beginning of class on Tuesday Solution must be coherent and clear as well as correct Solutions will be posted after the due date and will be available for 1 week No corrections

14. General Physics Lecture 1 14 Weekly Homework Grading Graded on 8 point scale with the extra three points devoted to quality of presentation issues Adequate diagrams Explanations of model Units and vector notation Algebra first (with symbols only), plug in numbers at the end Grading rubric - same as daily HW plus 3 extra pts 3:great presentation 2:minor presentation problems 1:major presentation problems 0:extremely poor presentation

15. General Physics Lecture 1 15 Guidelines for working homework problems Given: Find: Draw a picture! Write in pencil Clearly label units Cancel units when appropriate WRITE NEATLY Keep work in one column Box answers

16. General Physics Lecture 1 16 Class Time 5 Minutes at the start of class Professor will select two 2 minute problems from end of chapter Write quiz question # and answers on top of daily HW Group problems Lab-style activities SHORT lectures Classes will be ACTIVE! They will require you to participate and engage in the problems and activities.

17. General Physics Lecture 1 17 Preparing for Class Assigned Reading One or two chapters each class Usually one chapter Sometime two chapters will be assigned Go through exercises in each chapter Answers are provided at the end of the chapter Attempt two minute problems while reading Daily Homework
